How to use

import {Component} from '@angular/core';
import {GridsterComponent, GridsterItemComponent} from 'angular-gridster2';

@Component({
  standalone: true,
  imports: [GridsterComponent, GridsterItemComponent],
  ...
})

<gridster [options]="options">
  @for (item of dashboard; track item) {
  <gridster-item [item]="item">
    <!-- your content here -->
  </gridster-item>
  }
</gridster>

Initialize a simple dashboard:

   import { GridsterConfig, GridsterItem }  from 'angular-gridster2';
   options: GridsterConfig;
   dashboard: Array<GridsterItem>;

   static itemChange(item, itemComponent) {
     console.info('itemChanged', item, itemComponent);
   }

   static itemResize(item, itemComponent) {
     console.info('itemResized', item, itemComponent);
   }

   ngOnInit() {
     this.options = {
       itemChangeCallback: AppComponent.itemChange,
       itemResizeCallback: AppComponent.itemResize,
     };

     this.dashboard = [
       {cols: 2, rows: 1, y: 0, x: 0},
       {cols: 2, rows: 2, y: 0, x: 2}
     ];
   }

   changedOptions() {
     this.options.api.optionsChanged();
   }

   removeItem(item) {
     this.dashboard.splice(this.dashboard.indexOf(item), 1);
   }

   addItem() {
     this.dashboard.push({});
   }

Note: The gridster will take all the available space from the parent. It will not size depending on content. The parent of the component needs to have a size.

Having iFrame in widgets content

iFrames can interfere with drag/resize of widgets. For a workaround please read this issue #233

Interact with content without dragging

Option 1 (without text selection):

<gridster-item>
  <div (mousedown)="$event.stopPropagation()" (touchstart)="$event.stopPropagation()">Some content to click without dragging the widget</div>
  <div class="item-buttons">
    <button class="drag-handler">
      <md-icon>open_with</md-icon>
    </button>
    <button class="remove-button" (click)="removeItem($event, item)" (touchstart)="removeItem($event, item)">
      <md-icon>clear</md-icon>
    </button>
  </div>
</gridster-item>

Option 2 (with text selection):

<gridster-item>
  <div class="gridster-item-content">Some content to select and click without dragging the widget</div>
  <div class="item-buttons">
    <button class="drag-handler">
      <md-icon>open_with</md-icon>
    </button>
    <button class="remove-button" (click)="removeItem($event, item)" (touchstart)="removeItem($event, item)">
      <md-icon>clear</md-icon>
    </button>
  </div>
</gridster-item>
